Patent DE-3338058-A1 (DE)
Title: Fuel supply device
Inventor: STAPPEN PETER
IPC: F02M71/02
Filed: 1983-10-20
Abstract: A fuel supply device for mixture-compressing internal combustion engines is proposed, in which the pressure differential of the extracted air required for metering of the fuel quantity can be controlled. The device comprises a fuel metering device and a vane cell pump for generating a carrier air flow, which delivers the fuel through feed lines into the intake pipe of the internal combustion engine. A control valve designed as a differential pressure valve influences the pressure of the air at the fuel outlet point and thereby the differential pressure for the fuel metering. The differential pressure valve has a diaphragm, which on the one hand is acted upon by the air pressure upstream of the throughflow aperture of the differential pressure valve which prevails in one duct section, which is connected to the main air duct. On the other hand the diaphragm is acted upon by the air pressure which prevails in the carrier air duct downstream of the throughflow aperture and in addition by a force of one or more bimetal springs which can be varied as a function of engine variables. When the temperature rises, the bimetal spring serving for warming up is drawn against a stop by means of a pressure capsule acted upon by the intake pipe pressure, the intake pipe pressure being controlled by a temperature-dependent switch.

Title: Mine
Inventor: SCHMIDT ROLAND ING GRAD
IPC: F42B23/00
Filed: 1983-12-15
Abstract: A spherical mine has an explosive charge (2) and a plurality of circumferentially distributed jet engines (3, 4, 5) with a radial direction of thrust for moving the mine forwards on the ground (58). Each engine (3, 4, 5) is assigned a sensor which determines the position of the engine (3, 4, 5) in relation to the horizontal. Engines (3, 4, 5) oriented horizontally only approximately are each ignited by means of a logic circuit. A constant change in direction of the forward movement of the mine thereby takes place. Finally, there is a contact or proximity sensor which ignites the explosive charge (2) when the mine strikes a tank. <IMAGE>

Title: Output circuit having electronic overload protection
Inventor: KOSIC DRAGAN DIPL ING
IPC: H03K17/082
Filed: 1983-12-29
Abstract: The output circuit having electronic overload protection is a universal output stage which is composed of logic or processor circuits, is voltage-controlled by means of the 5 V digital signals, produces output signals of an order of magnitude of 20 to 30 V, and can at the same time cope with current overloads up to 2 A. The essential feature of the invention is that a resistor is connected in series in the emitter-collector circuit of a transistor (T3), in order to sample the magnitude of the output current, as a result of which the majority of the voltage drop takes place on the resistor (R1) and not on the transistor (T3). No forced cooling of the transistor is therefore required, and its life is thus also extended. A further transistor (T2) and a diode (D2) carry out the function of a current limiter. A capacitor (C1) with resistors (R6 and R7) delays the resetting of a flipflop (M) so that the circuit is not unnecessarily disconnected if only a random and brief overload occurs at the output. The signalling with the aid of a light-emitting diode (LD1) indicates the output state of the circuit according to the invention, but has no significant influence on correct operation of the circuit itself. The frequency of the output state sampling, if defects occur, is 2 Hz, which is sufficiently low to avoid unnecessarily loading the circuit. However, the correct operation of the circuit depends on ...   Original abstract incomplete. <IMAGE>

Title: Process for regenerating adsorbents in adsorption units, especially molecular-sieve cartridges, of a drying appliance, and drying appliance for drying material held in a drying-material container
Inventor: ROTH PAUL DIPL ING
IPC: B01D53/04
Filed: 1984-03-31
Abstract: In a process for regenerating adsorption cartridges of a drying appliance for heat-sensitive material to be dried, the adsorbent is dried with hot air and is then cooled via a part stream of the dry air used for drying the material to be dried. Said dry-air part stream is then returned to the dry-air main stream, specifically before the latter flows through the adsorption cartridges. As a result, the part stream is cooled by mixing with the dry-air main stream before being passed on for drying the material to be dried. Consequently, excessive heating of the dry-air stream used for drying, which could damage the material to be dried, can be avoided. The drying appliance used to carry out this process has a bypass line which is connected to the adsorption cartridges and, upstream of the adsorption units, debouches into a return line.

Title: Outside rear view mirror for motor vehicles
Inventor: MITTELHAEUSER BERNHARD
IPC: B60R1/076
Filed: 1985-04-02
Abstract: The invention is based on outside rear view mirrors for motor vehicles, it being possible for reasons of safety to fold down the head which accommodates the mirror body in the direction opposite to the direction of travel of the vehicle and a snap connection which is effected by means of a leaf spring being provided between the base and head of the mirror. As a result of the invention, the disengagement resistance of this connection is to be and/or remain large, while the engagement resistance is to be small. For these reasons, the base engages by means of a projection into a bend of the leaf spring, the bend, which takes the form of a recess, being situated between two contact positions of the leaf on the head and the section of the leaf spring situated between these contact positions being bent in such a way that the said section is shortened by bending when the head is retracted and the section runs onto the projection as a result, and is virtually released from one contact point.
